* Updated the haproxy fuzzers to build again.
* The frame decoder needs additional updates since we need to call init_h2 to initialise a memory pool. Disabling this for now as this is a larger change in the code base and will fix up in the coming week.
* Fixed hpack decode.
* Updated the yaml since we dont want memory sanitizer.
This makes build_fuzzers work with local checkouts.
Without this, it complains with 'Cannot use local checkout with "WORKDIR
/src".'

When build log is not found, skip it and avoid 404.
Fixes exception

Make some other changes:
1. Refactor fuzz_target.py and fuzz_target_test.py
2. Introduce pyfakefs and parameterized as dependencies and use them
in tests.
3. Fix infra-tests in CI so that they use installed dependencies
After the addition of Python 3.8 in #3874, the default python3 is
now /usr/local/bin/python3. The nanopb Dockerfile hardcoded a path
of /usr/bin/python3, causing again problems of Python packages being
installed for different version than attempting to run with.
* libzmq: build libsodium with --disable-asm to avoid false positives in MSAN checks
* libzmq: set autoconf install prefix to avoid /usr/local being added to the linker library paths
A non-working version of the standard library is installed in oss-fuzz's images
under /usr/local/lib. Using it breaks MSAN's tests with false positives.
Set the prefix in autoconf to something different from the default
/usr/local, as /lib is added by autoconf automatically to the linker
flags, which means this broken standard library is used instead of the
instrumented one in /usr/lib.
